Multiplicity of infection (moi) is a measure of how many phage particles infect a given bacterial cell within a population.

A value of MOI = 1 implies that on an average there is a single host cell for a single phage particle.

If 100,000 viral particles are added to one million host cells, the MOI is 0.1 means lytic cycle. High MOI means lysogenic cycle.

If the number of phage particles is two or more, it is more likely to produce lysogney. And as the numbers of phage per cell become lower and lower, the tendency toward lytic infection increases, and as it becomes higher and higher, the likelihood of lysogeny similarly increases.
